PULLINGr-OVER MACHINE FOR BOOTS AND SHOES.

To all whom it may concern:

Be it known that I, WVALTER SI-IA\V, of Boston, in the county of Sulfolkand State of Massachusetts, have invented an Improved PullingOverMachine for Boots and Shoes, of which the following is a speci fication,reference being had to the accompanying drawings, in which- Figure 1 isa plan of one of my machines; Fig. 2 is a sectional elevation on line 22of Fig. 1; Fig. 3 is a sectional elevation on line 33 of Fig. 1; Fig. ais a section on line 4t4 of Fig. 1; Fig, 5 is a section on line 55 ofFig. at; Fig. 6 is a section on line 66 of Fig. 1; Figs. 7 and 8 arelongitudinal sections of the throat and adjacent parts, each 90 from theother; Fig. 9 is a section on line 99 of Fig. 3. Fig. 10 is an elevationpartly in section on line 10-1O of Fig. 11, of the clamp hereinafterreferred to; Fig. 11 is a section on line 11-11 of Fig. 10.

In lasting boots and shoes the first work done after the last is inplace in the upper, is to pull the edges of the upper over the last atthe toe, the heel and at one or two places on the sides, and to tack itat the places where it is pulled over, the usual practice being to useone tack at the heel, one at the toe, and two or three at each side.After the pulling over is done the work is ready for the lasting machineor for hand lasting, pulling over being a preparatory process.

One feature of my invention is the novel mechanism for holding the lastand upper which consists of an outer gage and inner gage adapted to holda last within a shoe upper between them, and mechanism actingsubstantially to cause the outer and inner gages, as soon as the last inthe upper has been placed between them to hold the last and upper inplace during a portion of the revolution of the machine.

Although a back gage, somewhat like my back gage B, has long been known,I am the first to use a like gage on the front or outer side of a lastor boot or shoe on a last; and while my front gage is especially usefulin a machine with pincers, it is obviously well adapted for use in othermachines in which the upper or sole of a boot or shoe is to be operatedupon while on the last.

Another feature of my invention is the combination of a work holderhaving an outer gage and the pincers with mechanism Specification ofLetters Patent.

to move the pincers with relation to the outer gage, so as to pull theupper over the last while the other side of the upper is held by theouter gage and additional mechanism to move the outer gage and thepincers as one in order to present the last and upper to the tacker orother fastening machine; that is the first movement of the pincers is amovement with relation to the outer gage while the second movement ofthe pin-cers is not with relation to the outer gage; but both outer gageand pincers are moved with relation to the fastening machine.

Another feature of my invention is the combination of pincers,including, of course, means to cause them to take hold of and releasethe upper, with two mechanisms one for moving the pincers across thesole in a direction to give a pull on the upper nearly parallel with thesurface of the sole, and the other, connected with and operated by themovement of the first, for moving the pin cers in a direction away fromthe surface of the sole while the first mechanism is operat ing to movethe pincers to pull the upper across the sole.

A fourth feature of my invention is the combination with a fasteningmachine and pincers, of means to shift the pincers with relation to thenozzle of the fastening machine, for it is desirable when pulling theupper over at the sides of the last that the pincers shall be at oneside of the nozzle of the fastening machine, and when pulling the upperover at the toe that the pincers shall be in front of the nozzle. Thisshifting of the pincers is wholly new with me, and is of much practicalimportance in many styles of shoes.

The starting and stopping mechanism of the machine is controlled by atreadle connected to treadle rod E and rod E is moved in one directionby the treadle and in the opposite direction by spring a and isconnected at its upper end to one arm of lever 6 whose fulcrum is shaft7?. (Figs. 2 and 3.) The other arm of lever e engages block 6 mounted indisk E fast on shaft E see Figs. 4 and 5, and while in engagement withthat block prevents shaft E from rotating and also holds block 6 out ofthe path of lug c projecting from driving pulley E. Block 0 is mountedin a socket in disk E and is acted on by a spring 6 also mounted in thatsocket so that when lever e is operated to free block 6 block e isprojected by its spring 6 into the path of lug e which then engagesblock 6 and turns disk E and also shaft E to which that disk is fast.Lever c is connected to one end of a springc the other end of which isconnected to the frame of the machine and when lever e is releasedspring 0'' operates'thatlever so that its vertical arm is moved backinto the path of block 0 and as block 0 approaches that arm of lever cit is acted on by an incline on the end of lever c and moved back intoits retracted position in disk E against spring 6 and out of engagementwith lug 6 thereby disconnecting shaft E and driving pulley E, so thatwhen block 0 has moved far enough to engage the shoulder on lever 6further movement of shaft- E is prevented. Fast to disk E is a cam.projection e and as disk E revolves projection e actuates a throw offlever 15* pivoted on shaft k which engages the upper end of treadle rodE and disconnects it from lever e, which is then moved into itsoperative position by spring 6 Spring 0 is connected at one end totreadle rod E and at its other end to a slotted arm depending from leverE and when it is desired that shaft E shall continue to revolve as longas treadle rod E is depressed. spring 6 is connected on the right of theslot in throw off lever E instead of on the left as shown in Fig. 4,'and this change moves the throw off lever E into an inoperativeposition. When the lever E is thus shifted into its inoperative positionthat arm of said lever which engages the rod E is carried into positionabove and rests on the top of the head on the upper end of the rod E,and that arm of said lever E which is engaged by the projection c ismoved out of the path of said projection. Of course when lever E isswung into this inoperative position it is necessary for the operator toretingage the head of rod E with lever c after the lever E has beenshifted.

The tacker may be of any usual construction, and in the form shown thedriver and driver bar H and its actuating mechanism, the nailway h andthe hopper h will be well. understood without detailed description. Thehopper of the tacker is revolved by a belt 7& which is actuated by apulley fast on shaft 7L and shaft ha is driven by a belt connectingpulley h on shaft 72 with a pulley 71f on the hub of driving pulley E.

The nozzle G is secured to the block 9 which is fast to bracket 5 andabove the nozzle is the separator 9 see Figs. 7 and 8, which is actuatedby pinion g and pinion is in mesh with gear 9* driven by rack hen thedriver H is not raised by its cam and connections, or in the positionshown in Fig. 2, bell crank 9, one arm of which engages rack 9 holdsrack against its spring 9 and the separator is then in position toreceive the lowermost tack in the nailway it, that is the tack slot inthe separator coincides with the nailway and the lowermost tack is heldby its head in the slot in separator 9 Bell crank is engaged andoperated by the connecting rod of the driver bar mechanism as will beclear from Fig. 2

and when driver bar H is raised bell crank is operated by the connectingrod of the driver bar mechanism, and moves rack g, gear and pinion g andthus revolves separator 9 so as to carry the tack-receiving aperture 9from the nailway h around to tack chamber g before plunger H is liftedabove the aperture 9 The tack falls, point first, and lodges betweenretainers 9 until driver H is moved down to drive the tack.

The outer gage A is fast on the end of rod a which is mounted in asleeve a supported by the frame of the machine and sleeve (4 has mountedon it a clamp a which is operated by a lover a and caused to engage ordisengage rod (4 to lock that rod to sleeve a or to free it from thatsleeve. The operator places the last and upper between the two gages Aand B, gage A being then held by a spring a within rod (4, so far fromgage B as to allow the operator to adjust the edge of the upper on oneside of the last between the open jaws of pincers D, D and the outergage A is then pressed against the upper near the opposite side of thelast as shown in Fig. 2 and locked in that position to sleeve (4 bylever 11 and clamp a. As means for automatically operating lever a andclamp a when the machine is started I have shown a'lever (Z which isacted upon by a cam (Z fast to shaft E and lever (Z is provided with atoe a which engages lever a and when the machine is started the toe a oflever (Z is raised and a spring a fast to the frame of the machine aiseslever a and operates clamp 64 and locks rod a to sleeve (1 As shown inFigs. 10 and 11, the clamp a is fixed to the lower ends of two stems aand these stems at their upper ends are pivotally connected to the levera Lever a is made with a tail piece o so that when the longer arm ofsaid lever is swung upwardly this tail-piece engages a lug a on sleevea, thereby pulling up on the stems a and causing the clamp (1, to griprod (4. The end of the sleeve a has fixed to it a tongue (4 whichprojects into the rod (4 and. serves as an abutment for the spring a Theforward end of lever (Z is arranged above an arm (Z fast on rock shaft(Z journaled at its ends in links f which are connected at their forwardends to carriage f in which the pincer-s D D are mounted; and on rockshaft d is also fast an arm (i the free end of which arranged above andengages a roll mounted on the upper end of the pivoted aw D of thepincers. Jaw D of the pincers is pivoted on a stud projecting fromcarriage f and has fastened to it one end of a spring (Z the other endof which is fastened to that stud with provision for adjustment as shownin Figs. 1 and 6; and spring (Z serves to hold jaw D in engagement witharm (Z and through rock shaft (Z holds arm (Z in engagement with theforward end of lever (Z and lever (Z against cam (Z.

The links f are connected at their rear ends by a pin which is also thefulcrum of lever (Z and that pin also connects links f with one end ofslotted lever f which is vibrated by bell crank lever f loose on rockshaft journaled in the frame of the machine. Lever f" carries a cam rollwhich is engaged by a cam F on shaft E The fulcrum of lever f is a studon block and block f is mounted in one arm of a lever f which is pivotedon shaft E The other arm of lever f" is a segmental gear which mesheswith a segmental gear f fast to rock shaft ((7. Handle D is one end of alever pivoted at a, the other end of the lever being segment f so thatby moving handle D and therefore segment f lever f can be swung on shaftE and fulcrum block f adjusted in the slot of lever f to vary the extentof movement of carriage f.

hen the pincers D D are moved in one direction by lever f the gages Aand B and the last with the upper on it are held stationary and thepincers pull one side of the upper over the last while the other side ofthe upper is held by gage A which at that time is stationary but afterthe upper has been pulled over the last by the movement of the pincersin one direction and while the pincers are being moved in the opposite,direction the gages and the last with the upper on it move in the samedirection with the pincers, to present the last with the upper on it tothe tacker. To provide for this movement of the gages sleeve (4 ismovable on the frame of the machine and is connected by link a to ablock mounted in slotted lever a and lever is pivotally mounted on shaft(2- and carries a cam roll which is engaged by a cam A fast on shaft Ewhich cam is properly timed with relation to cam F. hen the extent ofmovement of pincers D D is varied it is also de sir-able that the extentof movement of the holder be varied accordingly so that the pincers andholder may move together toard the tacker, and for this reason that endof link a which is connected with slotted lever a. is also connected bya link to an arm fast to shaft so that when shaft (Z7 is turned toadjust fulcrum block f link will also be adjusted.

The pincers D D are connected directly to a bracket D and that bracketis supported by two eccentrics D whose shafts D connect bracket D withcarriage f, as

plainly shown in Fig. 6. Each shaft D carries at its upper end a pinionwhich meshes with the handled gear D Fig. 1, so that by moving thathandled gear the pincers are shifted on carriage f. The carriage f, asshown in Figs. 3 and 6, is made in two parts bolted together, betweenwhich the shafts D are confined in vertical grooves or recesses providedin the meeting faces of the two parts of the carriage. In Fig. 6, whichis a view from the front of the machine, the face or outer plate of thecarriage is shown as removed. In pulling over at the toe it usually isnecessary to have the pincers in front of nozzle G, and this is. in somecases, true also in pulling over at the heel; but in pulling over at thesides it is desirable to have the pincers at one side of the nozzle Gr.hen pulling over at the toe and heel the front gage A is just above thesurface of thesole, and does not act as a clamp. The down hold A aidsthe operator, but may be turned to one side into an inoperative positionwhen desired.

In order to move carriage f vertically while it is being movedhorizontally (by links f levers f and f and cam F) I provide levers fwhich are mounted upon the frame of the machine and connected at theirforward ends to carriage f. These levers f are operated by movement oflinks f and act when so operated to move carriage f vertically whilecarriage f is being moved horizontally by links f Levers f are pivotedat f and have arms f which. as shown in Fig. 2, bear against the stops funder the influence of spring F. Slotted lever f operates links f andthereby carries stops f out of contact with arms f so that spring F canact to raise carriage f.

The operation is as follows: When the machine is stopped the outer gageA is unlocked and thrown out by its spring a and all the other parts arein the position shown in Fig. 8. The operator places the last and upperagainst the inner gage B, with the edge of the upper between the jaws ofthe pincers D D, and presses the outer gage against the opposite part ofthe work, as shown in Fig. 2. As soon as the machine starts the pincersD D are closed and the rod a which carries the outer gage A is locked.by the motion of lever (Z, caused by cam (Z fast to shaft E and pincerspring (Z that is ca'm (Z allows the cam roll end of lever (Z to movetoward the axis of shaft E and thereby allows spring (Z to close pincersD D, by allowing arms (Z? and (Z of rock shaft (Z to move under stressof spring (Z and thereby allowing jaw D, to move on its axis so that itsnipping end nips the upper between it and the nipping end of jaw D. Thismotion of lever (Z also moves toe a and allows spring a to actuate levera and thus causev clamp a to lock the rod a of gage A to clamp sleeve a.The pincers D D having thus nipped the upper are moved away from thesurface of the sole by the stress of spring F which acts through leversf on the carriage f, which is pinned to the levers f, and also pinned tothe links f and these links f are moved endwise by the slotted lever fwhich is vibrated by cam F through bell crank f. In order to vary thethrow of pincers D D the fulcrum block f of slotted lever f is adjustedby moving segment f. which meshes with a segment fast to lever f whichcarries fulcrum block It will now be clear that as the slotted lever fis rocked by cam F (fast on driving shaft E the links 7"- will be movedcndwise to carry the pincers D D over the surface of the sole; but thismotion of the links f carries stop f away from one arm of levers j, andthe spring l then exerts its force through levers f to move the pincersD D away from the surface of the sole; and the resultant of these twomotions is the motion desired for the pincers D D. During this movementof the pincers D Dthe outer gage A takes much of the strain whilepulling over at the sides and materially lessens the labor of theoperator and enhances the quality of the work. The downhold A and innergage 13 also assist in holding the work especially when pulling over atthe toe and heel. It will be clear that I may adjust the mechanismtending to give a positive movement over the surt'ace of the sole withrelation to the movement caused by the spring so that I may have, ifdesired, a considerable positive pulling movement before the yieldingspring movement begins. I may also reaoily adjust the tension of springii so that the desired movement of the pincer-s away from the surface ofthe sole may be had. hen the pincei's D D have thus pulled the upperover the last (taking about half a revolution of cam F and shaft i l)the pincers D D and both gages A and B move back to bring the last andupper into proper relation to the nozzle G- ot the tacker; the gage Abeing moved back. (torcing the 13 back against its spring) by means of(ram A", slotted link a, fulcrumed on shaft link a and clamp sleeve (1,in which rod a is then clamped as above de scribed. The pincers D D aremoved back by about a quarter of a: revolution of cam F, and this takesplace While gage A is being moved back. As soon as the work is thusbrought into proper relation with nozzle G a tack is driven; and thefurther revolution of cam F carries stops f against levers f and therebyswings levers f against the force of spring F, and cum 4 actuates lever(Z to open the pincers D D by moving jaw D against the force of spring(Z At the end of the last quarter revolution of shaft D the block 6 iswithdrawn from engagement with lug c and brought into engagement withthe shoulder on lever (B, as above described. Rod (4 of gage A isunlocked by the latter part of the revolution of cam A7 and thrown outby its spring a What I claim as my invention is:
